To stay ahead, financial institutions are turning to quantum-safe technologies. Quantum Key Distribution (QKD) offers unbreakable communication channels based on the laws of physics, while Post-Quantum Cryptography (PQC) brings quantum-resilient algorithms to existing digital infrastructure.
In this article, we explore how these technologies are being deployed to protect the integrity, privacy, and resilience of financial transactions before quantum computers reach full power.
Case: Secure financial transactions with QKD and PQC
Banking and payments rely on encryption to safeguard data and assets. QKD generates encryption keys using quantum states, which cannot be intercepted without detection. PQC uses advanced mathematics to create algorithms that are resistant to attacks by quantum computers. Both are essential to future-proofing interbank transfers, payments, and digital banking services.
Business value
- Future-proof security: Protects sensitive transactions from emerging quantum threats before they materialize.
- Regulatory assurance: Meets new and upcoming requirements for secure communication and data protection.
- Brand differentiation: Demonstrates proactive leadership in cybersecurity and risk management.
- Business continuity: Reduces risk of breaches that could disrupt operations or erode customer trust.
Technology readiness
QKD is already in early commercial deployment in regions like Asia and Europe, though it requires specialized infrastructure.
PQC is easier to implement at scale and is undergoing standardization by bodies like NIST. Financial institutions are testing PQC integration into communication protocols, payment systems, and data storage. Full adoption will unfold over the next five to seven years.
Leading players and experiments
ID Quantique, Toshiba, and Quantinuum are delivering QKD hardware and services to financial institutions and governments.
Mastercard, Visa, and SWIFT are piloting quantum-safe encryption methods for secure payments and messaging networks.
European Central Bank and Bank of England are exploring PQC as part of their digital currency and critical infrastructure strategies.
Thales and PQShield provide post-quantum cryptographic solutions for integration into banking infrastructure.
